Description

Technical Field

[0001] This utility model relates to plastic hardware, and in particular to the structure of a rebound device for opening and closing cabinet doors. Background Technology

[0002] To facilitate opening and closing cabinet doors, handles are usually installed. However, handles are not aesthetically pleasing and protrude from the cabinet door surface. Not only are low-positioned handles prone to causing foot injuries, but they are also difficult to operate when users have limited hands. Therefore, a spring-loaded mechanism can be installed between the cabinet body and the door. When the door needs to be opened, simply press the door lightly to automatically spring it open, effectively improving both aesthetics and ease of passage.

[0003] The cabinets and doors where the push-pull mechanism is installed have a certain distance between them, and different cabinets have different distances. To meet the installation needs of these cabinets, the push-pull mechanism needs to have a certain degree of adjustability. Existing push-pull mechanisms are mainly adjusted through a screw and nut pair. When installing the push-pull mechanism, the nut needs to be screwed onto the screw first, then adjusted to the appropriate length, and then fixed in place. This operation is relatively cumbersome.

[0024] This utility model proposes a rebound device structure.

[0025] The rebound device structure of this embodiment includes a housing 1, a movable inner cylinder 2 inside the housing, a hollow cavity in the inner cylinder, and an adjusting seat 3 installed at one end of the inner cylinder. The adjusting seat has a threaded adjusting groove 31. An adjusting hole 11 is opened on the housing opposite to the adjusting groove. An adjusting wheel 4 with threaded teeth is located in the adjusting hole inside the housing. The adjusting wheel protrudes from the adjusting hole and engages with the adjusting groove to drive the inner cylinder to move through the adjusting seat. A latch 5 for fixing the cabinet door is movably installed in the cavity at the other end of the inner cylinder. An opening and closing assembly that connects the adjusting seat and the latch and drives the latch to move is also installed inside the inner cylinder.

[0026] like Figure 1-6 The outer shell and its components are mounted on the cabinet. The cabinet door is equipped with a self-locking component that is connected and fixed to the latch. When the cabinet door is pressed, the self-locking component, latch, and opening / closing assembly are activated in sequence, thereby fixing or disengaging the self-locking component from the latch and opening / closing the cabinet door. When adjustments are needed to accommodate the cabinet and cabinet door, the operator can use their fingers to turn the adjustment wheel. This rotation causes the adjustment seat, inner cylinder, opening / closing assembly, latch, and other components to move relative to the outer shell. The movement can be directed towards the cabinet door to shorten the distance or away from the cabinet door to increase the distance, thus achieving adjustment and meeting the installation needs of different cabinets and cabinet doors.

[0027] The described rebounder structure includes a housing 12 that is hollow inside and open on one side, and a cover plate 13 installed on the side opening of the housing. The inner cylinder 2 is installed inside the housing, which facilitates the installation of internal components. The outer wall of the housing 1 is provided with fixing ears 14 for fixed installation on the cabinet.

[0028] The aforementioned rebound mechanism includes a sliding block 6 located inside the inner cylinder 2 and movable along its cavity. A latch 5 is connected to the outer end of the sliding block. A spring 7 is connected between the inner ends of the sliding block and the adjusting seat 3, i.e., the ends located inside the inner cylinder and adjacent to each other. The inner end of the sliding block is also provided with a locking groove 61. A pull rod 8 is installed on the adjusting seat 3, and the end of the pull rod is a hook 81. The hook is located in the locking groove and can be locked and fixed with the locking groove. The spring applies a pushing force to the sliding block, so that the locking groove and the hook are hooked and fixed. The latch on the sliding block is locked with the self-locking part on the cabinet door. Until the cabinet door is pressed, the sliding block moves toward the adjusting seat, the locking part on the locking groove disengages from the hook, and the latch also disengages from the self-locking part on the cabinet door, so that the cabinet door can be opened smoothly. The inner ends of the adjusting seat 3 and the sliding seat 6 are respectively provided with protruding seat posts and positioning posts. One end of the spring is sleeved on the seat post and the pull rod 8, and the other end of the spring is sleeved on the positioning post, thereby achieving positioning and preventing the spring from falling off or misaligning. This also makes the structure more compact and small. The locking groove is set on the positioning post so as to cooperate with the hook on the pull rod. The locking groove includes an annular groove 62 with a recessed ring. The middle of the annular groove is a locking platform 63. The locking platform has a V-shaped recessed locking groove 64 on the side facing away from the adjusting seat 3 and a V-shaped protruding guide part 65 on the side facing the adjusting seat. A V-shaped protruding guide block 66 is provided on the inner wall of the annular groove opposite to the locking groove. An inlet groove 67 extends from the inner wall of the annular groove opposite to the guide part towards the adjusting seat. The V-shaped ends of the inlet groove and the guide block are respectively arranged opposite to the same side of the V-shape of the guide part and the locking groove. Figure 4-6 As shown, when the cabinet door is open, the hook of the pull rod is located at the guide groove, opposite to the right side of the V-shape of the guide. When the cabinet door is pressed, causing the slide to move towards the adjusting seat, the hook first contacts the right side of the V-shape of the guide, and then moves along the right side of the annular groove to the right side of the guide block. After the cabinet door is stopped being pressed, the spring pushes the slide outward, and the hook moves along the right side of the guide block to the bottom of the V-shape of the locking groove, thus achieving locking. If the cabinet door needs to be reopened, pressing the cabinet door again will cause the hook to move along the left side of the locking groove to the left side of the V-shape of the guide block, which is opposite to the left side of the annular groove. After the cabinet door is stopped being pressed, the spring pushes the slide outward, and the hook moves back along the left side of the annular groove to the guide groove, thus completing the reset. This locking groove structure is relatively simple and operates stably and accurately. Furthermore, the cavity of the inner cylinder 2 is provided with a groove 21 along the moving direction of the slide block 6, and a slider 68 is provided on the slide block to move along the groove. The groove and the slider are used for limiting and orientation to ensure the accuracy of movement. Similarly, the adjusting seat 3 can also be provided with a positioning block 32 inserted into the groove 21 to form a positioning and improve the connection stability. In addition, the other end of the pull rod 8 is an annular positioning ring 82, and there is a pressure block 9 arranged opposite to the positioning ring. Rivets 10 or pins are arranged sequentially through the inner cylinder 2, the positioning ring, and the pressure block, thereby fixing the adjusting seat and the pull rod to the inner cylinder.

[0029] The aforementioned rebound mechanism has a self-locking component 20 installed on the cabinet door and fixedly connected to the latch 5. The self-locking component has a ball head 30. The latch 5 has two elastic gripping ends 51 that can hold the ball head. When the latch moves into the cavity of the inner cylinder 2, the two gripping ends are pressed and hold the ball head, thereby forming a fixed connection and closing the cabinet door. When the latch exits the cavity of the inner cylinder, the two gripping ends spring open and release the fixation to the ball head.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
